DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 432,009, dated July 15,1890.

' Application filed December 3, 1889. $erial No. 332,488. (No model.)

To all whom it may concern..-

Be it known that I, GEORGE G. BAKER, a citizen of the United States,residing at Chillicothe, in the county of Peoria and State of Illinois,have invented certain new and useful Improvements in Door-Locks; and Ido hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled inthe artto which it appertains to make and use the same.

My invention has for its objectan improvement in door-latches ordoor-fasteners, in which by placing it in its proper position a doorwill be firmly secured from the inside, so that it will be impossiblefor any one to open the door from the-outside.

It may be more fully understood by reference to the accompanyingdrawing, in which- The figure shows the device in central longitudinalsection in its position holding the door.

In the figure, B represents a cut section of the door, and A a cutsection of the doorjamb. 0 refers to a steel bar, D to a case inelosingthe bar G, E to a catch-lever, which is properly pivoted, and J K toshoulders or projections from the case.

In operation, the door being open, the case D is removed from the bar 0and the sharpened projection L is inserted into the doorjamb up to theshoulder and the bar C is against the side of the door-jamb andcontinues out beyond the outer edges of said door-jainb. The door beingclosed,the frame orcase D is then passed over the bar 0.

The catch-lever E being depressed to allow its passage over the baruntil the shoulders J K contact with the door-jamb on one side and thedoor on the other, when by releasing the catch-lever the spring whichoperates the lever throws the point of said lever into one of a seriesof perforations or holes in the bar, thus securely fastening the door.This bar is made of highly-tempered steel and the projecting part ismade into a sharp blade,

so that it can be easily inserted into the wood of the door-jamb.

The blade L at the end of the bar 0 may be inserted by merely placingthe bar against the side of the door-jamb and the point of theprojection L touching the wood. Then by closing the door it will be seenthat the sharp portion'L will be forced into the wood of the door-ja1nb; but ordinarily it can be inserted by merely pressing in with thefingers. The case D may be cast or may be made in any way desired.

The particular advantage in this style of door fastener or lock is thatit prevents the opening of the door from the outside. It is made in asmall and convenient form, which may be carried in the pocket or in. asatchel, so that when rooms with old doors and poor locks are occupiedby attaching this device or look it firmly secures such doors, or, infact, any door to which it is applied. The ordinary door-lock has alwaysan opening on the outside for the insertion of keys, and through whichthose skilled in opening or picking locks may secure an entrance; but itwill be seen that this device when properly placed is not accessible byany tool which may be used by professional lock-breakers and is completeprotection, against them.

Having thus fully described and shown the uses of my invention, what Iclaim, and desire to secure by Letters Patent, is

In a door-securer, the metal bar 0, having a series of perforations andthe blade L, the hollow casing D, which carries the bar 0, having thearms .I K, the lever E, attached to the casing D and provided withsuitable spring device, all substantially as described and set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEO. G. BAKER.
